Some feedback on the gameplay. 

I recommend adding some means of having the camera follow the direction the ship is facing. Like when you steer the ship to a certain direction, maybe after a brief delay, the camera follows the ship's direction?

Also, maybe tweak the throttle mechanic. I kept changing the camera completely down when i tried increasing the throttle. Maybe adding an indicator of where the "enemy is detected" will help the player too.

Since there's no map (which i don't think can be included, given the screen space), maybe showing like an arrow, or maybe even highlighting the screen edge to signify where the enemy is.

Or maybe even when taking damage. Helps the player to see where the target is.

My phone was on vibrate, and it kept vibrating whenever I tried moving the joystick. May not be the best choice, since if I keep trying to move, the phone will constantly be vibrating in my hands. In fact, i think it vibrated for every action i did with a tap on the screen, but not sure.

That's what I got for now.

thanks for your feedback! yes vibration has definitely a tad overboard we will dial it in with the next update that will focus on optimizations .

we are addressing many of these issues, with regards to throttle we will probably have both the option to have the throttle hide itself as well as a non hiding variant. Some people do prefer to have as much of the screen space not cluttered by UI as possible so this way we can please both preferences. damage indicators will be added (probably at a later update after the optimizations depending on the workload) so that people are alerted to where they are getting hit from.

great feedback! thanks to this we have a better idea about what to prioritize, we encourage all our users to come and drop feedback such as this to help us figure things out.
